Vacuum insulation composite polymerized polystyrene board

The utility model discloses a vacuum heat insulation composite polymerized polystyrene board which comprises a board body, a bottom board is arranged at the rear end in the board body, a supporting mechanism is arranged on the front face of the bottom board, and the front face of the bottom board is movably connected with a supporting board through the supporting mechanism. By the adoption of the structure, the bottom plate, the supporting mechanism and the supporting plate can play a role in supporting the plate bodies, after the plate bodies are collided, the supporting mechanism drives the supporting plate to reset, it is avoided that the plate bodies deform and affect the attractiveness, the plate bodies can be longitudinally connected through the plate body connecting assembly, and the plate bodies are not prone to deformation. The position of the connecting block can be stabilized through the positioning mechanism and the fixing mechanism, the situation that the position of the plate body is affected by
